PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 634,819, dated October10, 1899. hpplication filed April 13, 1899. Serial No. 712,907. (1i 0model.)

and State of Pennsylvania, have inventednew and useful Improvements inPrinting- Presses, of which the following is a specification.

In certain lines of printing it is frequently necessary to make partialchanges of formas, for example, in printing railway-tickets, transfers,labels, and the like, where the body of the form remains the same andthe completed articles difier from each other only in the matter ofcontaining different dates, The ordinary porate the same in the body ofthe form where they are to appear and then to print directly from thetype, stopping the press, lifting the form, and changing the linesrequired, or to make as many separate plates of the whole form as thereare to be changes and substitute one plate for another when a change isrequired.

The object of my invention is-to provide effective, simple, andeconomical mechanism for accomplishing the purpose stated withoutstopping the press; and to this end my invention consists in thefeatures of construction and the combination or arrangement of partshereinafter described and Y claimed, reference being made to theaccompanying drawings, in which- Figure 1 is an end view illustrative ofthe relation between the impression-cylinder and the differentprinting-cylinders. Fig. 2 is an edge view of the impression-cylinderand one of the spindles operated thereby and containinga removableprintingsleeve. Fig. 3 is a perspective view of one of the spindles withthe detachable printingcylinder. removed. Fig. 4.- is an end'view of thesame, the two parts being shown in locked position.

In carrying out my invention I employ an ordinary impression-cylinder 1,a roll 2 of the web of paper to be printed, a cutter 3, and a main orprimary printing-cylinder designed to carry the blank-spaced form and tocooperate with the impression-cylinder to print a yondthe periphery ofsaid cylinder.

blankspaced form-that is to say, a ticket, label, transfer, or likeobject-in such manner as to leaveblank spaces thereon at certainpredetermined points to be subsequently supplied with the requiredprinted matter to complete the same; The impression-cylinder 1 isprovided with a gear-wheel rhich meshes with a pinion 6 on a spindle 7parallel with the shaft on which the impressioncylinder is mounted andlocated slightly be The spindle? is provided with a cylindrical head 8,having an annular shoulder 0 thereon'adjacent to its inner end; The saidhead 8 is also provided with a groove 10, which is adapted to bereceivedby a feather or spline 11 in the printingsleeve 12, having one or moreplates 13 screwed or otherwise'secured to its outer surface andcontaining the matter to beprinted in the blank spaces left in theticket or other form. The said sleeve 12 fits snugly upon the head 8 ofthe spindle and is locked in place thereon by means of a washer 14,which fits over the extended threaded end of the spindle 7 and engagesthe outer edge of said sleeve. The washer 1i is itself held in place bymeans of a split washer 15, which also embraces the end of said spindleand is forced inwardly and locked by means of nut 16.

In the foregoing description I have referred to but one spindle 7 andthe parts cooperating therewith to provide the secondary printingmechanism, which prints in the aforesaid blank spaces in the formprinted by the main or primary printing cylinder or mechanism. It willbe obvious, however, that I may use a plurality of said spindlescontaining printing cylinders or sleeves having different matter thereonfor the purpose of printing in the different blank spaces left in theticket, label,

. or the like by the blank-spaced form of the main or primary printingcylinder or mechanism.

Suitable inking devices will of course be provided for the printingcylinders or mechanisms; but it is not considered necessary to describethe same.

Constructed as above. described it will be observed that if it bedesired at any time to change the matter which is to be printed in theblank spaces on the form all that it is necessary to do is to loosen the'nut 16 on the end of the spindle '7, remove the split washer and themain washer l4, and then slip the sleeve 12 from its seat on the head 8.To apply another cylinder containing different form-matter-as, forexample, the date of the transfer or other ticket or the destination towhich the ticket is to be issued--it is simply necessary to place a newsleeve 12 on the head 8 so that the spline or feather 11 will fit withinthe spline way or groove 10, insert the washer 14 over the end of thenut 16, apply the split washer 15, and tighten said nut 16. WVhenapplied in this manner, the sleeve is held securely in place on thespindle, its proper registration with the blank spaces in the formprinted by the cylinder 4 being obtained by locating the feather orspline 11 in the printing-sleeve12 at such position that when it isengaged by the groove 10 the spaced-apart forms or printing-plates 13 onthe sleeve 12 will come directly opposite the blank spaces in the mainform. 7

It will be understood that the idea of my invention is to avoid thedelay incident to changing the plates on an ordinary rotaryprinting-machine for each change of form,

the lost time being that which is necessary to screw or clamp the platein position on its cylinder and to adjust the same for register after itis on. It is frequently necessary to build up low and defective plates,and this is usually accomplished by pasting overlays on theimpression-cylinder, which overlays of course are not only useless onthe next change of form, but require scraping off and renewing to suitthe next change. I paste them to the back of the plate before it'isscrewed onto its sleeve, thus insuring its permanency and obtaining amaterial saving in the operation of making ready the form, as theunderlay being between the plate and sleeve cannot be displaced. This ismaterial and important and is a great time-saving factor in changes ofsmall editions, which require a complete stoppage of an expensivemachine for a very considerable part of the time and verymateriallyreduces the production. I propose to have in stock a quantity ofprinting cylinders or sleeves which have plates thereon containingdifferent form-matter to be printed in the blank spacesin the main formalready madeready and imposed to register without adjustment, and whenit is desired to change all that is necessary to be done is tosubstitute one sleeve foranother, the removal of the old sleeve and theapplication of the new one being effected in the manner heretofore setforth.

It will be seen thatin the construction'and combination described forfirst printing a form with blank spaces and subsequently printing anydesired matter in said blank spaces the provision of the cylindricalheads and sleeves with interlocking grooves and splines or feathersarranged in the manner set forth is advantageous, desirable, andimportant in that by merely slipping the sleeves on the cylindricalheads and causing the grooves and splines or feathers to interlock thesleeves are not only forced to turn with the cylindrical heads, but thegrooves and splines or feathers constitute registering deviceswherebythespaced-apartprinting-forms on the sleeves without further attentionor manipulation are caused to accurately register with the blank spacesof the form on the main or primary printing-cylinder, as hereinbeforeexplained. Although I have described and shown the spline or feather inthe sleeve and the groove on the cylindrical head, they may be reversedwithout altering the function of these parts.

Having now described my invention, what I claim as new, and desire tosecure b y Letters Patent, is

1. In a printing-press, the combination with an impression-cyli-nder,and amain printingcylinder designed to print a form containing blankspaces to be subsequently supplied with printed matter, of a spindlehaving a cylindrical head provided with a register-groove, a cylindricalprinting-sleeve detachably mounted on said head and provided interiorlywith a register-spline and exteriorly with a spacedapart printing-platefor printingin the afore-' said blank spaces, the groove and splinebeing arranged to cause registration of the spaced-apart printing-plateson the sleeve with the said blank spaces of the main printing-cylinderas the sleeve is placed upon the cylindrical head, substantially asdescribed.

2. In a printing-press, the combination with an impression-cylinder, anda main printingcylinder designed to printa form containing blank spaces,of a spindle having a cylin= drical head geared with the impression-cyLinder and constructed with a register-groove, a cylindricalprinting-sleeve lengthwise removable from the cylindrical head andprovided interiorly with a registenspline and exteriorly withspaced-apart printing-plates to register with the aforesaid blank spacesto print the required matter therein, said groove and splineinterlocking and arranged to cause registration of the saidspaced-apartprinting plates with said blank spaces and devices fordetachably holding the printing-sleeve on the cylindrical head,substantially as described.
